...

Cause

The issue is corrected in scope of request APSI-537 and fixed in Wordpress APS application version 4.6.1-235.

Resolution

Import the latest Wordpress APS version and use it for provisioning.

There are two possible workarounds in order to fixed a failed task for an older Wordpress version.

The first possible workaround is the following:

  1. Comment the following block inside /var/www/vhosts/1/<webspace_id>/webspace/siteapps/WordPress-<instance_id>/htdocs/wp-includes/class-phpmailer.php (the exact path is found in the task error message):

    public function setFrom($address, $name = '', $auto = true)
{
    $address = trim($address);
    $name = trim(preg_replace('/[\r\n]+/', '', $name)); //Strip breaks and trim
    // Don't validate now addresses with IDN. Will be done in send().
//    if (($pos = strrpos($address, '@')) === false or
//        (!$this->has8bitChars(substr($address, ++$pos)) or !$this->idnSupported()) and
//        !$this->validateAddress($address)) {
//        $error_message = $this->lang('invalid_address') . $address;
//        $this->setError($error_message);
//        $this->edebug($error_message);
//        if ($this->exceptions) {
//            throw new phpmailerException($error_message);
//        }
//        return false;
//    }
    $this->From = $address;
    $this->FromName = $name;
    if ($auto) {
        if (empty($this->Sender)) {
            $this->Sender = $address;
        }
    }
    return true;
}
  2. Re-submit the task afterwards.

As another way to resolve this issue it is possible to set a valid address for $from_email variable in /var/www/vhosts/1/<webspace_id>/webspace/siteapps/WordPress-<instance_id>/htdocs/wp-includes/pluggable.php. Then resubmit failed task.
